As the public then moves into the security, both the security and the OBV will surge ahead. If price movement precedes OBV movement, Granville calls this a "non-confirmation." Non-confirmations can occur at bull market tops, when the security rises before/without the OBV or at bear market bottoms when the security falls before/without the OBV...
